The rx and tx data packets are samples encapsulated in vrt headers for
IF data: http://www.digitalif.org/
The control protocol is just a bunch of enums and structs in a header
shared by firmware and host:

These kind of contributions would be highly appreciated.
Thanks,

If there's a succinct protocol description out there for UHD-over-UDP
I'd start work on a Wireshark/PCAP
protocol parser, and perhaps even submit an Internet-Draft describing
the protocol, if there's interest.
